5.25 days, since you would divide 7,560 watt hours by 1,440 and get 5.25

How do you solve 192 divided by 3/4

Basile [38]

Answer:

256

Step-by-step explanation:

so the basic problem is 192 divided by 3/4, so you flip the second fraction around. So the problem is now 192*4/3.

Find the volume of the solid obtained by rotating the region bounded by the given curves about the speciﬁed axis. y = 64x−8x^2,

Mandarinka [93]

We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />
